I've don the Small FFT test. Power consumption jumps up to 52W bufore I panic and change the power limit to 40W. But otherwise, temperatures jump to 65C, rising up to 80C before I stop the test. Only PL1/2 lights up in limit reasons .

An i7-8550U reaching 80W is really alarming. Even my 8250U runs at most 52-53W with no undervolt. Seems like 4.0GHz requires an extremely high voltage. The 8250U and 8550U are identical processors anyway, just one processor requires a higher voltage. 8th Gen CPUs aren't anything special. If you compare with 6th gen i5-6200U and 7th gen 7200U, the 8th gen 8250U has double the cores, resulting in less double the performance at double the power when tested at the same clock speed. Because that's just Intel being desperate on 14nm+++++++++ and struggling on 10nm whilst AMD is set on 7nM by 2019.

But normal consumers don't know this.

That being said, it really don't think that laptop hardware is designed to run at 2x or even 3x the power it was designed for (Ahem manufacturers designing for 15W when 8th gen U cpus clearly require 30+W to perform well. Power Limits are scattered everywhere in the BIOS. ThrottleStop has access to one of them. RW-Everything and XTU have access to another one. Remember, if your laptop has a hidden power limit it is really difficult to mitigate this without knowing the datasheet for your BIOS. I tried to control my right fan but nothing would work, I could only control the left fan, so I ended up doing a hardware modification. (disconnecting the PWM lead of Fan 1 and connecting it to the PWM header of Fan 2).

EDIT: Hitting PROCHOT after 2 and a half minutes either means you let the TDP sky high or that's some terrible cooling. Probably the latter because ThrottleStop TS Bench only draws about 30W for me

It handled it pretty well, then. Mine lights up every alarm in under a sec then lights itself off after a while lol

I'm skeptical with AMD. They're introducing great changes for the market, but they're still "new" at leading this game, and can't afford too much R&D. Intel coasted for too long on Sandy Bridge, and is now paying for it. Time for Intel to step up on R&D, which won't be difficult since they're absurdly rich. Like AMD plus 10

I love competition. For one, they made the U processors 4c/8t, and HQ processors 6c/12t.
Looking forward to see my laptop become absurdly obsolete in the following years, honest

My previous Y50 had an interesting "feature" that it would NEVER put its fans on 100%. 99°C? Yeah, just run the fans at what, 50%?
However, when updating the BIOS, the fans would be extremely loud, and you knew it could do something more than that puny original output.
ppl found out that if you disconnected the PWM cable, the fan would run at 100%. And they found out that they could buy some small temperature-activated switches on Aliexpress. They glued the little temp switch on the heatsink pipes and voila, it would turn on at 100% for a couple of seconds on the chosen switch temperature. I did it on mine at 75°C and it was amazing. Instead of running at 90°C, it would run at, behold, 70°C.

Why Lenovo didn't do it originally baffles me.

Sometimes I think some brands are dumbOr we're not seeing the big picture.

Terrible cooling is a compliment.

Can't blame them, though. It was designed for 15w, and does the job at 15w greatly. There's just not much headroom. It hit PROCHOT at 32~33W, 3.7GHz.
I found that 3.5GHz sits below 90°C on ThrottleStop 1024M test. It's good enough without changing the thermal paste.which I totally don't wanna do, because last time I changed the thermal paste on my previous Y50, the best I managed to get was 1°C higher than the stock thermal paste, after trying several new methods, previously unknown to me (I'm a mustard drop guy)
And I used the Gelid GC Extreme.

Hi folks. I want to use Throttlestop to limit my turbo multiplier and undervolt my cpu. I know how to set both of those in FIVR - but my question is: do I need to press the "Turn On" button on the throttlestop front page for those multiplier limits and the udnervolting to take effect, or do they take effect immediately on saving, even if I don't "Turn On"? Also, do I need to reload Throttlestop every time I restart for those same multiplier limit/undervolt to take effect?

Turn on/off only affects Clock Modulation, Chipset Modulation, and Set Multiplier in the main interface.

Hello guys, I have a problem with ThrottleStop, after I restored Windows 10 and followed this guide to start it on startup, now it no longer appears in the taskbar but remains only in the background, I followed the guide carefully but nothing more appears.
Any suggestions to solve this problem?

The Task Scheduler works great but it has some default options that need to be disabled. The following guide has lots of pictures so you will be able to see exactly how the Task Scheduler should look when you are done.

For this example, I created the folder C:\Program Files (x86)\ThrottleStop and I unzipped all of the ThrottleStop files into that folder. If you ever drag a ThrottleStop folder from one folder or directory to a new folder or directory, delete the ThrottleStop.INI configuration file. This will force ThrottleStop to create a new ThrottleStop.INI configuration file with the correct read / write attributes. The pictures are from Windows 7 but the Task Scheduler is pretty much the same in any version of Windows.

1) Open the Task Scheduler. On the left side, highlight the Task Scheduler Library folder and then on the right side, click on Create Basic Task...

2) In the Name box, enter ThrottleStop

3) If you want ThrottleStop to only run in the background and you do not want a user to have any access to the user interface, for Task Trigger select, "When the computer starts". If you want the ThrottleStop user interface to be available from the Task Bar or System Tray, select, "When I log on".

4) In the Action window select, Start a program

5) Click on the Browse... button and navigate to where you have ThrottleStop.exe located.

6) When you get to the Summary tab, check off, "Open the Properties dialog for this task when I click Finish".

7) Now you can go back and double check to make sure the Create Basic Task wizard set things up correctly. On the General tab, if you want access to the user interface, make sure, "Run only when user is logged on" is checked. If you want ThrottleStop to quietly run in the background, make sure "Run whether user is logged on or not" is checked. In either situation, check off, "Run with highest privileges".

8) If you want ThrottleStop to only be running in the background, the Triggers tab should look like this.

9) The Actions tab should show the program that you want to run.

10) For the Conditions tab, make sure nothing is checked. Some boxes will be checked but grayed out. You need to click on the box above any of these boxes so that you can clear the box that is grayed out. When done, nothing should be checked.

11) Same thing for the Settings tab. Make sure everything except the top box is clear. The only box that I have checked is, "Allow task to be run on demand".

If the goal is to make sure that Speed Shift is running all the time, start ThrottleStop, click on the TPL button, and check off, "Enable Speed Shift when ThrottleStop starts". Click on OK. This setting enables Speed Shift when ThrottleStop starts or when you resume from Sleep or Hibernate mode with ThrottleStop running in the System Tray or Task Bar or if ThrottleStop is running in the background. To test your new task, restart Windows.

If you want to make sure that Speed Shift is enabled after you resume, restart HWiNFO after you resume so it can re-sample your current CPU state. It should show SST in green if everything is OK.

Edit - Here is an example of what happens when HWiNFO is started first and Speed Shift is enabled after HWiNFO has already started.

MSR 0x770 is set to 1 so Speed Shift is definitely enabled but HWiNFO does not update the SST flag in real time so it is still showing red. That is why you need to restart HWiNFO after Speed Shift is enabled. I think some people have forgot to restart HWiNFO so they might think that Speed Shift is disabled when it is really enabled. I am using the Windows High Performance power profile so the 800 MHz confirms that Speed Shift is likely enabled.

Choose the option called "When I log in" instead of the option called "At startup".
